Six Workers Found Dead at Colorado Dairy, Authorities Suspect Gas Exposure

Six men were found dead Tuesday at Prospect Valley Dairy, a large farm east of Keenesburg, in what investigators believe was a tragic accident involving toxic gas. Officials identified all six as Hispanic workers, including one teenager who was still in high school.

Rescue crews were dispatched after reports of multiple people unconscious inside a structure at the facility. The Southeast Weld Fire Protection District confirmed the men were discovered in a confined space where they had likely been overcome by hazardous fumes. Despite efforts, all six were pronounced dead at the scene.

The Weld County Sheriff’s Office has said there are no signs of foul play, pointing instead to a possible industrial accident. Occupational Safety and Health Administration (OSHA) investigators have joined the inquiry to determine what type of gas was present and how the exposure occurred. Confined spaces on dairies can sometimes trap methane, hydrogen sulfide, or other byproducts of animal waste and equipment, creating deadly conditions.

The dairy, which operates as part of the Dairy Farmers of America cooperative, expressed deep sorrow in a statement, offering condolences to the families and pledging to cooperate fully with authorities. The deaths have shaken the local agricultural community, raising renewed concerns about worker safety and the dangers farm laborers face in environments where hazardous gases can accumulate quickly.
